WireGuard vs OpenVPN Overview

In the recent past, this has been the hot news on the internet. I must admit that I also took some time to join the dots by reading from various sites. Eventually, I understood the real difference between WireGuard vs OpenVPN.

WireGuard vs OpenVPN

I cannot lie that this is something you will understand easily. However, I have tried to put everything that you need to know about these two types of VPNs. I have also added some most repeated process that may confront you while setting up a VPN.

The main issue that is causing this misunderstanding is that most people are comparing WireGuard and OpenVPN without creating a consistent benchmark. This is distorting the whole process of comparison.

Why WireGuard

There has been a lot of VPN protocols emerging in the last few years. However, none has hit me except WireGuard. I am a heavy user of the OpenVPN but something captured my attention in WireGuard.

This new type of VPN aims at simplicity. You can set it up without reading ten pages of ‘How To…’ pages. The software is free and open-source license. Note that it has the same license as the Linux kernel, which has never disappointed me. All this made me ask myself why did WireGuard, having so many other VPNs around, grew steadily like a bush-fire.

Few Lines of Code

I learned that WireGuard VPN has around 4000 lines of code compared to the OpenVPN, which weighs to 600,000 total lines of code. This affects the efficiency and speed significantly. The smaller system ensures that you can troubleshoot faster and it is also less prone to attacks.

WireGuard benefits from extremely high-speed cryptographic primitives and deep integration with original operating system kernel, so speeds are high with low overhead.

Simple Setup

As I told you earlier, I will not spice anything up. VPN is not a cup of tea. I see it being stubborn even to people who have been using it for ages. However, for WireGuard, it is relatively easy. Although it does not make it a baby class project.

It can take up to six hours reading how to set up WireGuard. This is much simpler compared to the OpenVPN precisely the large-scale OpenVPN-based network.

Additionally, it is currently not included in the operating system which requires installation of the customer’s software and a kernel module. Eventually, WireGuard will be included in the kernel for smartphones and macOS, Linux, and other operating systems.

Security Weaknesses

As I said earlier, this is a new VPN. This show that the OpenVPN has not been passed through security checks. For it to be authenticated and verified, it undergoes through numerous tests on various processes. There is also a period of pilot program that welcomes the views of the users. Therefore, you should not rely fully on WireGuard until it completes these process and pass. It is not worth where you need ultimate security.

Stability

The WireGuard utilizes most benefits of the UDP protocol. Package loss cannot cripple the connection. Uses a preliminary finishing point for connectivity. They can exchange servers as they maintain all connections. The client can exchange networks without leaving the connection.

Is OpenVPN still Outstanding?

The OpenVPN comes with major drawbacks, but it is still the best protocol in town. You cannot gamble your security and risk using WireGuard when you have the OpenVPN. This doesn’t mean that I am again WireGuard fully. I use it when I am able to take the risk of my security. I love its simplicity and speeds.

Why is OpenVPN still on Top

However, for big firms and firms that will not compromise their security even a quarter-inch, just let WireGuard get tested and adjusted the remain security check-ups.

Having said much, we can check on the advantages of using OpenVPN protocols:

Encryption

The openVPN uses an OpenSSL library which provides encryption of both the data and control channels. Additionally, OpenSSL gears a great number of cryptographic procedures. For instance AES, 3DES, RC5, and Blowfish. It lets the OpenSSL carry out the authentication and encryption work. This allows the OpenVPN to use all ciphers that are available in the OpenSSL package.

Similarly, it uses the HMAC package as an authentication feature to add a layer of protection in the connection (termed to as “HMAC Firewall” by the developer). Just like IKEv2, IVPN gears AES with 256-bit keys.

Security

The good news is that OpenVPN has no vulnerabilities concerning safety. It is regarded as secure primarily when it is implemented with a safe encryption algorithm and credentials for authentication.

Speeds

When it is used in its  UDP mode with a good network connection, OpenVPN delivers like IKEv2. Relatively, the WireGuard is much fast than the OpenVPN because of the shorter number of codes.

Setup

Setting up and configuring an OpenVPN is not simple task for anyone. Especially those were doing it for the first time. You can spend hours trying to set up as you follow written procedures. It is hardest while setting up an OpenVPN for large-scale use.

Stability

The OpenVPN is stable and efficient in wireless, cellular, and other networks that are not reliable. They are prone to package loss and congestion. The OpenVPN has TCP method for the unreliable connections. This mode disadvantages substantial performance because of the incompetence of compressing TCP.

 

How to use OpenVPN

How to Connect to an OpenVPN Server

  1. Download the OpenVPN client installer. You’ll need to use a connection program called a “client”. The client handles the connection between your computer and the OpenVPN server. You can download the client from here. Use the “Installer” download link that matches your version of Windows.

You’ll need to know if you are running a 32-bit or 64-bit version of Windows. Press the Windows+Pause, then look for the “System type” entry.

  1. Run the installer. Run the OpenVPN installer after downloading it. Confirm that you want to run it. Follow the instructions to proceed, and leave all of the settings at their default. All of the necessary services will be installed so that OpenVPN can function properly.
  2. Download the configuration files for the server. Any server that is running OpenVPN should provide you with a set of configuration files. One of the files may be a security certificate. The other file will contain the server information. There may be multiple server configuration files if your VPN service offers multiple servers.

These configuration files can be found on your VPN service’s Support page. The configuration files mostly come packed as zipped files.

You can connect even if you are not getting the configuration files. See Step 9 of this section.

  1. Copy the configuration files to the proper folder. Copy the key and the configuration file(s) to the C:\Program Files\OpenVPN\config folder for OpenVPN. It may be located at C:\Program Files (x86)\OpenVPN\config instead.
  2. Right-click on the OpenVPN shortcut and select “Run as administrator”. You must run OpenVPN as an administrator.

Ensure that the OpenVPN is not running before starting this step.

  1. Right-click on the OpenVPN icon in your System Tray. You’ll see a list of servers based on the files that you copied into the OpenVPN config folder.
  2. Select the server you want and click “Connect”. The server will prompt you to enter your username and password. You received these credentials when you signed up for the VPN service.
  3. Confirm you are connected. You’ll see a notification appear indicating that you are connected to the VPN server. Your internet traffic will now be sent through the VPN.
  4. Connect to the VPN without configuration files. You may still be able to connect and download the correct files.

Start the OpenVPN then enter the IP address/hostname of the server.

Enter your username and password when prompted.

Select your profile if prompted.

Select “Always” when prompted to accept the certificate.

Verdict

 openvpn connect

OpenVPN is the best choice for all platforms. It is extremely fast, secure, and reliable. The IVPN Multihop network is available when connecting via OpenVPN only. The minor drawback is the requirement to install the software as a client but, on mostly, this only takes some minutes.

On the other hand, WireGuard is a promising VPN with high speed, high efficiency, strong encryption, and low overhead, but may not yet be ready for production environments.

Wrapping it Up

Just that WireGuard is still under heavy development and not yet ready for general use. Most people are still checking whether they can make it their primary VPN protocol.

The truth is that WireGuard is not complete, it has not passed a security audit, and the developers warn the users about using and trusting the code.
